August Fishing in Galveston: Summer’s Last Big Bite

As summer winds down, Galveston’s fishing scene stays red-hot. August may bring the year’s warmest water, but it also delivers steady action for anglers who know how to time the tides and beat the heat. Whether you’re starting early to chase Redfish and Trout inshore or heading offshore for a shot at Kingfish, Snapper, or Mahi, this month offers one more round of peak-season fishing before the transition to fall begins.

At Up Above Adventures, we know how to make the most of August conditions. Let’s explore the weather, fish patterns, and gear tips that will help you hook up and cool off with a successful summer send-off.

August Fishing Forecast: Summer’s Final Surge

August Fishing in Galveston

August brings some of the warmest air and water temperatures of the year to Galveston, with daytime highs in the 90s and Gulf waters hovering in the low to mid-80s. These conditions can make the middle of the day a grind — but they also keep fish feeding consistently during the early morning and late afternoon windows.

Calm mornings are common, offering smooth runs offshore and steady inshore conditions, while afternoon sea breezes and the occasional thunderstorm are part of the daily rhythm. Planning your trip around the weather is key, especially later in the day when pop-up storms are more likely near the coast. As thunderstorms move through the area, they can trigger feeding frenzies among predatory fish. The drop in barometric pressure often causes fish to become more active and feed aggressively. While it’s never ideal to get caught in a storm, having one pass nearby — whether you’re fishing inshore, nearshore, or offshore– can create prime conditions for an exciting bite in saltwater.

Water clarity can fluctuate quickly after rain or wind, especially in the bays and nearshore zones. After a storm, targeting areas with cleaner water — often near current lines or deeper channels — can make all the difference. Offshore, the water tends to stay clearer and more stable, making it a smart option when weather allows.

August is all about smart timing and flexibility. With the right plan and a little patience, this month offers one last stretch of top-tier summer fishing before fall patterns start to take over.

What’s Biting in August? Big Bites Before the Cooldown

Even as summer starts to wind down, the bite across Galveston’s bays and offshore waters shows no signs of slowing. Here’s what you can expect to reel in this month:

  • Inshore: Redfish and Speckled Trout continue to feed aggressively at dawn and dusk, especially along marsh drains, oyster beds, and grassy shorelines. As the sun climbs, they tend to move into deeper channels and shaded structure. Flounder are still active around sandy bottoms, marsh edges, and boat cuts — especially on moving tides.
  • Nearshore: Spanish Mackerel, Jack Crevalle, and Sharks are thick around the jetties, reefs, and current lines just off the beach. Watch for diving birds and surface explosions that signal feeding frenzies. On calm mornings, Tarpon may roll near bait-rich areas along the beachfront, offering a shot at one of Texas’s most prized gamefish.
  • Offshore: August is prime time for big-game fishing offshore. If Red Snapper season is still open, limits are possible on wrecks and deep reefs. Kingfish are fast and plentiful, while Mahi-Mahi and Cobia hang around weed lines, floating debris, and buoys. Deepwater ledges and structure may also produce Grouper, Amberjack, and even Tuna or Wahoo for anglers making the long run.

So, where are these summer species hanging out?

Reel Hot Spots: Where to Find the August Action

Knowing where to fish is just as important as knowing when. In August, Galveston’s waters are full of life — but specific locations offer the best shot at hooking into quality fish.

  • Inshore: East and West Galveston Bay are go-to spots during early morning and late evening hours. Look for Redfish and Trout around grass lines, oyster reefs, and marsh drains — especially where cooler water and bait movement intersect. The stretch from Eagle Point to April Fool Point remains a consistent producer for Flounder, thanks to its mix of structure, current, and sandy bottom.
  • Nearshore: The Galveston Jetties are loaded with life this time of year, offering access to Mackerel, Sharks, and Jacks within a short run. Reefs and rocky patches just outside the surf zone also hold steady action, particularly where bait schools are present. Keep an eye out for rolling Tarpon near current breaks and deeper troughs along the beachfront.
  • Offshore: Wrecks, rigs, and natural reefs continue to produce Red Snapper, Kingfish, and Grouper. Weed lines, color changes, and floating debris attract Mahi-Mahi and Cobia. For those willing to go the distance, deeper ledges and bluewater zones may yield Wahoo, Tuna, and even the occasional Sailfish.

Best Times to Fish in August: Beat the Heat, Time the Bite

With high temps and steamy afternoons, fishing in August is all about hitting the water at the right time. Fortunately, the fish are still feeding — you just need to know when to catch them in action.

  • Early Morning: This is prime time for inshore success. Cooler water temperatures spark feeding activity from Redfish, Trout, and Flounder. Topwaters and live bait produce great results before the sun climbs too high.
  • Midday: Offshore fishing holds strong even as temperatures rise. Deep reefs and rigs offer consistent bites for Kingfish, Snapper, and Grouper. Just be prepared for the heat — bring plenty of water, shade, and sunscreen.
  • Evening: As the day cools down, inshore species often slide back into the shallows. Redfish and Flounder are especially active near marsh edges and drains on an outgoing tide. Just because the sun goes down doesn’t mean the fishing has to stop. Waterfront subdivisions can be excellent spots to target red drum and speckled trout under the lights. Many homes along the water have dock lights, overhead lights that shine on the surface, or even underwater green lights. These lights attract baitfish, and where there’s bait, predator fish are never far behind. Not only do these areas produce quality fish, but they also offer a great opportunity to beat the heat and enjoy some productive nighttime fishing.

Tides & Conditions:

  • Incoming tides bring baitfish and draw predators into shallower feeding zones.
  • Look for cooler water pockets or clearer water after storms — these areas can quickly become fish magnets.
  • Watch for surface activity like birds, bait busts, or slicks to pinpoint hot spots in real time.


Tackle Box Tricks: August Essentials & Smart Summer Tactics

Inshore:

  • Baits: Live shrimp and croaker are go-to choices, especially in the early morning. Soft plastics and paddle tails in natural tones work well when fish get picky.
  • Gear: Medium-action spinning combos with 20-30 lb braided line and fluorocarbon leaders offer strength and sensitivity. A good topwater plug is a must for those early dawn blowups.

Nearshore:

  • Baits: Spoons, cigar minnows, and live baitfish will attract Spanish Mackerel, Jack Crevalle, and Sharks. Use flashy, fast-moving presentations when fish are feeding near the surface.
  • Gear: Step up to heavier tackle with wire leaders to handle toothy predators. Keep a rod rigged and ready for fast-moving schools or unexpected Tarpon sightings.

Offshore:

  • Baits: Sardines, squid, and ribbonfish are all solid picks for Snapper, Kingfish, and Grouper. For Mahi or Cobia, rigged ballyhoo or live bait near weed lines can be deadly.
  • Gear: Bring high-capacity reels with strong drags, circle hooks for bottom fishing, and trolling setups if covering ground. Don’t forget a gaff for landing larger fish!

And no matter where you’re fishing, bring the summer staples:

  • Polarized sunglasses
  • A wide-brim hat
  • UV-protective clothing
  • A cooler with ice-cold drinks

A well-prepped tackle box means more time fishing and less time troubleshooting under the August sun.
